Rustdoc-LLMs – Generate Rust llms.txt file for AI context prompts

Rust documentation helper that helps a Rust crate developer generate a file llms.txt that helps provide context to large language models (LLMs).

Thanks to excellent work by the Rust team, rustdoc team, and rustdoc-md team.

Install:

Use the tool when you're working on a crate and you want to document it:

The tool creates two files:

• target/doc/lorem_ipsum.json (this uses your own crate naming convention)

• target/doc/llms.txt (this is a markdown file created by rustdoc-md)

If you like, you can copy these files to the top level of your repository, which can make the files easier to add to version control and easier to find for search engines and AI systems:

This Rust crate is deliberately small and simple. The purpose is to make it slightly-easier to generate llms based on what's currently easy and available for Rust crate developers.

Currently this tool calls existing command line interfaces, using cargo and rustdoc-md with specialized compiler flags. If this tool is useful in practice, then I intend to iterate to add command line arguments, options, tests, and the like.

Pull requests are welcome. Issues are welcome.
